with hydroxylamine followed by deprotection gave L-adenosine 5'-carboxaldehyde oximes, whose enantiomers are known to be potent inhibitors of S-adenosyl-L-homocysteine (AdoHcy) hydrolase. The L-adenosine and its 5'-aldehyde oxime derivatives were found to be inactive as inhibitors of AdoHcy hydrolase. Docking calculations showed that binding of L-adenosine to AdoHcy hydrolase is weaker (higher energy)
2',3'-O-异亚丙基-L-腺苷的Moffatt氧化,用羟胺处理所得的粗制5'-醛,然后脱保护,得到L-腺苷5'-甲醛醛肟,已知其对映异构体是强力抑制剂S-腺苷-L-高半胱氨酸(AdoHcy)水解酶。发现L-腺苷及其5'-醛肟衍生物作为AdoHcy水解酶的抑制剂是无活性的。对接计算显示,与D-Ado相比,L-腺苷与AdoHcy水解酶的结合更弱(能量更高),特异性更低(簇数更多)。
